External Wall Insulation in Clifton
EWI systems that insulate solid walls externally and finish them in a warranted render topcoat.
If you are weighing up external wall insulation in Clifton, the starting point is what your walls are actually built from.
Bristol is characterised by dense Victorian terraces, Georgian stone in the older centre and postwar suburban estates, with cement render trapping damp in solid-wall Victorian terraces the recurring theme on the properties we survey.
Local conditions bring a mild, wet south-western climate, and that has a direct bearing on which systems are worth specifying. Much of the older stock is solid-wall bath and pennant stone, where lime rather than cement is the correct specification.
When external wall insulation is the right call. Choose EWI on solid-wall, no-fines or non-traditional construction where you want a genuine thermal upgrade rather than just a new finish.

FAQs
External Wall Insulation in Clifton
Will EWI make my house look different?
The walls become 70-200mm thicker, so reveals get deeper and the eaves usually need extending. Done properly it looks intentional; done cheaply it looks like a box.
Can EWI cause damp?
Correctly specified it reduces damp risk by keeping the wall warm. Problems come from poor detailing at reveals, sills and penetrations, or from using a non-breathable system on a wall that needed one.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
Will you need scaffolding?
For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.
